Just one of the details to making Kyusho work.
Kyusho works with rotation not linear attack.
Torque is nothing more than a measurement of twisting, or rotational, force. It generates far more than a straight line issuance of power and many fighters have talked about this since the early days of Boxing. Those old boxers always stated that you twist the glove on impact… it was for different reasons, but still they knew. They used it primarily to open a cut, preferably over the eye to have the blood drip into the eye and have a blinding affect… that would remain the target for the rest of the fight. They also knew it had far more impact even if it did not open a wound as the stretching with the impact made the hit far more effective.
So what makes torque stronger than linear power?
Let’s start with Kinetic energy; in physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is also defined as the effort or inertia needed to accelerate a given mass from rest to a specific velocity.
Kinetic energy is divided between linear kinetic energy and rotational kinetic energy. The overwhelming advantage of using the rotational technique is the greater ability to increase the speed of a strike over a given distance due to the greater acceleration path. This increased path of acceleration can be up to 1.5 times greater in the rotational as opposed to the linear technique.
Kinetic energy can also be passed from one object to another as in a game of billiards. This is observable when a player imposes kinetic energy on the cue ball by striking it with the cue stick. When the cue ball collides with another ball, it slows down dramatically and the ball it collided with accelerates to a speed as the kinetic energy is transferred to it. These are called elastic collisions, in which kinetic energy is preserved, (with inelastic collision, kinetic energy is dissipated in other ways or energies, such as heat, sound, breaking, etc.
Now it is also possible to combined linear and rotational energy for a maximum speed as well as transferable power level. So as you initiate the strike with a linear projection and at the very end add the rotational speed and force on contact, you will then gain the maximum affect.
But why is torque more influential with Kyusho on the opponent than the straight line kinetic energy transfer?
Most beginners try ballistic straight line power or force, which is why Kyusho does not work for them until they develop the correct touch with torque. But not only does it increase penetration power, there are many other vital components involved.
By using a rotation as seen, explained and demonstrated in the 6 Ji Hands DVD, we use this double power transfer for greater penetration into the target area. The nerve is more cleanly accessed as the action of the rotation serves in pushing the muscle structures aside. This gives a clear path to the nerve without the muscles protecting or padding the contact area from the weapon. It also serves to gain depth from the increased speed and velocity of the action.
In this action the nerve, once exposed and accessed, is also stretched making it far more vulnerable and reactive with greater results. The action can be instrumental in also pinching the stretched nerve against a basing object like a bone structure for an even more acute message to the brain. This can cause an overload of sensory input and trigger a safety mechanism in the body such as dropping to a prone position (via feinting, dysfunction or unconsciousness), for recovery.
Now if the target is in a muscular section of the body (as opposed to a head point with few layers of skin, fat and fascia), it also serves to attack the reflexive system taking it from somatic motor affect to more autonomic reflexive and subconscious level. This is accomplished by simultaneously affecting the Muscle Spindle Cells or Golgi Tendon Organ depending on where you struck. The same stretching action that will be issued on the nerve will also catch one of these two structures as well yield even greater effects on the opponent.
It also serves us in classical boxing or kick boxing and even the more modern MMA training, by adding that extra rotation on contact that the old boxers used. Let’s take the jab for example; most fighters will use linear power which stuns on contact but if the just learned to also drop the knuckles (even through gloves), down on impact, the results would be far greater and especially so when used on a Kyusho target. Take the chin as yet another example in this rotational energetic, if we jab straight in, there will be little discernable results other than a flinch or withdrawal of the recipients head. If we manage to drop the knuckles at the end of the jab on impact to the chin, then the angle to trajectory to access the nerve is accomplished and there will be far greater dysfunction, sense impairment or altered state of consciousness.
This also holds true for the cross, hook and uppercut… the 4 main strikes used in matches as well as street altercations. By learning the Kyusho targets and working them with the rotational strike, you will become far more powerful, potent and protected.
To summarize, we have:
• Increased acceleration of our attack
• Increased penetration
• Increased velocity of the strike at delivery phase
• Narrower base of power transference
Advantages of the rotational technique include:
• Practitioners do not have to be as big or as strong
• Greater variations in training for rotation technique compared to linear attack
• Tension required and strength needed for linear attack can be counterproductive as opposed to the relaxed and more fluent movement of the rotational attack
So the “torque” (measurement of rotational kinetic energy) in Kyusho is not measured by mechanical device, it is measured in physical result in training.
Sorry Vince energy is really real.
